Can´t open Mathcad. Only Error message appears.
Hello.
I just got the Mathcad15 from my school with the license code for the Student-Edition.
I installed everything and it also said that it was installed correctly and it is all finished.
Now I wanted to open it and it gives me following message:

The first line translated means that my requested license has a failure.
The last ones mean that i can press "Yes" to restart the license-setup-assistent and try open Mathcad again after that. That didn´t help.
Can somebody please help me?
Sorry for my bad english, I´m from Austria 😉
Kind regards
